A device, and its production method, the device has a substratenand a coating composition, the coating composition being formed by thengas phase or plasma polymerization of a gas comprising at least onenorganic compound or monomer. The polymerization is carried out usingna pulsed discharge having a duty cycle of less than about 1/5, in whichnthe pulse-on time is less than about 100 msec and the pulse-off time isnless than about 2000 msec. The duty cycle can also be varied, thus thencoating composition can be gradient layered accordingly. The device hasna coating composition which is uniform in thickness, pin-hole free,noptically transparent in the visible region of the magnetic spectrum,npermeable to oxygen, abrasive resistant, wettable and biologically non-fouling. |
